Contributing to the R Project for Statistical Computing and several open-source R
packages.

To help continue bringing in new talent, I have also been fairly involved in the
engineering hiring process.

I received an M.Sc. in Mathematics and the Foundations of Computer Science from
Oxford University, working with Joel Ouaknine in the area
of Software Model Checking. Prior to joining Google I was deeply involved in the
FreeBSD operating system, and was the primary
release engineer for the FreeBSD 4.x releases.
